DOD Model maps to OSI demonstrate as beneath:
IP is the convention that works at the Internet layer. It advances the parcels dependent on the system address (IP address) in the bundles and the steering tables.
The four layers of DoD demonstrate from Top to Bottom are:
1. Process Layer: Responsible for the usage of client level applications, for example, mail conveyance, document exchange, and remote login.
Another issue with Ethernet is again caused by CSMA/CD: the more devices you put on a segment, the more likely you’ll experience collisions, especially along with devices that constantly need access to the wire. For example, when two devices are on an Ethernet wire, you would not expect to see that many collisions since it would be unlikely that both devices would need to transmit data simultaneously. However, if 100 devices were on the wire, quite a few might need to send traffic simultaneously. When these devices since the wire and simultaneously send their traffic, a collision occurs. And the way CSMA/CD works, they need to create a JAM signal and back off a random time interval before sending again. Of course, the more devices present, the more likely that the “random” time interval they choose is the same as another device, thereby creating even more collisions, greatly slowing down a device’s access when trying to transmit data. On top of this, high-performance
PCs, network-based applications, and high-bandwidth applications such as video can create even more contention for access to the wire.
The Ubnt M2 400 antenna is firstly set to access point.
Then the installation of the station is done. I will tell you how to do this step by step configuration. Let’s first configure the access point side.
Describes how to make screenshots.
Secondly, configure the station side.

Following is a small script on how you can redirect non-payment/ expired PPPoE users to a page where he can be informed that his/her account has been suspended due to non-payment.
Also described are things to do on the radius side
/ip pool add name=expiredpppoe ranges=10.10.10.2-10.10.10.254 /queue type set 0
bfifo-limit=150000000 kind=bfifo /ip firewall address-list add address=1.1.1.1
list=radiusizin
Let’s enter the IP firewall mangle rule in the new terminal as follows.
Sometimes we want to prevent a harmful IP address.
Because the IP address we want to prevent can lead us to a malicious site or application.
Now we’ll explain how to do this step-by-step below.
First step; IP> Firewall> Address List>Name following
Second step; IP> Firewall> General>forward following
Third step; IP> Firewall> Advanced>Destion Address List following
Last step; IP> Firewall> Action>drop following
/ip firewall address-list
add address=1.1.1.1 list=Blacklist
add address=2.2.2.2 list=Blacklist
/ip firewall filter
add action=drop chain=forward comment=Blacklist dst-address-list=Blacklist
